Can you describe the specific routines that allowed Amir Shakkar to have Baba's vision from the Chavadi?

Yes, Chapter 22 outlines several routines that ensured Amir Shakkar had regular darshan of Baba from the Chavadi. Firstly, there was a daily morning routine where Baba would pass by the Chavadi while going for alms, allowing Amir to see Him as He went and returned. Secondly, there was a daily evening routine where Baba would come to the front of the Chavadi and salute all directions before returning to the Masjid. Finally, and most importantly, on every alternate day when Baba slept in the Chavadi, they were in close proximity, separated only by a plank door, and would talk with each other after the evening worship was over and other devotees had left.
